lawdog, I have a P-51D in paint right now. Not NMF but instead it's camouflaged. I'm using stencils for the national insignia a friend made on his Cricket machine. I like painting on the insignia much better that using decals. Since you use Montex masks, how do you keep from getting the thin edge of white around the insignia after you spray the blue? I've sprayed on the insignia on three models and this has been an issue on each one. Just curious to know how you get around this.
